Felipe has 3/4 acre of land to use for a vegetable garden. He separates the land into vegetable plots that are each 1/12 acre. How many vegetable plots does Felipe have? Explain how to use the number line to model this situation and find the answer.
Answers
Answer:
1) The number of vegetable plot Filipe has = 9 vegetable plots
2) A number line with 1/12 divisions will give the number of 1/12 acre vegetable plots as the number of divisions between 0 and 3/4
Step-by-step explanation:
1) The total size of the land Filipe has = 3/4 acre
The size of the vegetable plots to which he separates the land = 1/12 acre
The number of vegetable plot Filipe has = (The total size of the land Filipe has)/(The size of the vegetable plots to which he separates the land )
∴ The number of vegetable plot Filipe has = (3/4)/(1/12) = 9
The number of vegetable plot Filipe has = 9 vegetable plots
2) The number line can be used to model the situation by having the number line that has divisions of 1/12 unit and counting the number of 1/12 divisions between the zero (0) mark and the three quarter (3/4) mark
PLEASE GIVE BRAINLIEST!!
answer:
9 plots
explanation:
Felipe has 3/4 acres of land to use and she is dividing that into plots. Those plots are 1/12 of her acre so you divide 3/4 by 1/12
Which statement correctly identifies the mistake Joe made? in step 5, Joe should have added 1 to both sides of the equation instead of dividing both sides of the equation by --1. In step 2. Joe should have multiplied the first equation by 2 instead of by 3. in step 4, Joe simplified 27 + (-20) as 7 instead of simplifying to -7. In step 3, Joe multiplied the term -2y by 2 instead of by-2.
Answers
Answer:
This question is incomplete as it lacks the actual question. The question describes how Joe solved a system of equations step-by-step using elimination method. The steps used by Joe are as follows:
1. The equations given are: 2x + y = 9 and 3x - 2y = 10.
2. Multiply the first equation by 3 to get 6x + 3y = 27
3. Multiply the second equation by -2 to get -6x - 4y = -20
4. Add the equations to get -y = 7
5. Divide both sides of the equation by -1 to get y = -7
The statement that correctly identifies the mistake Joe made is: In step 3, Joe multiplied the term -2y by 2 instead of by-2.
Step-by-step explanation:
Elimination method of solving a simultaneous equation in Mathematics involves removing one variable in order to solve another variable. In this case of equations:
2x + y = 9
3x - 2y = 10
Joe eliminates the x variable in order to solve for the y variable first. To do this;
- In step 2, he correctly multiplies the first equation by 3 to get 6x + 3y = 27
- In step 3, he multiplies the second equation by -2 to INCORRECTLY get -6x - 4y = -20
Joe made a mistake in this step 3 because he multiplied -2y in the original equation (3x - 2y = 10) by 2 and not -2. He should have gotten -6x + 4y = -20 if he multiplied by (-2). That is (-2 × -2y) to give +4y.
Yoko, Bob, and Chang have a total of $120 in their wallets. Bob has $10 less than Yoko. Chang has 3 times what Bob has. How much do they have in their wallets?
Answers
Y = B + 10
C = 3B
Substitute:
(B + 10) + B + 3B = 120
5B + 10 = 120
5B = 110
B = $22
Y = B + 10
Y = $32
C = 3B
C = $66
A tanker truck fills the gas station’s reservoir at the rate of 12 1/2 gallons per minute.
If the reservoir was empty and it is now 35 gallons full, how long has the tanker been filling the reservoir?
Answers
Answer: 2.8 minutes
Step-by-step explanation:
If it takes 12.5 gallons per minutes to fill the reservoir, then we have to divide 35 and 12.5.
35 ÷ 12.5 = 2.8 minutes
Since it takes 12.5 gallons per minutes to fill the reservoir, it will take 2.8 minutes to fill the reservoir.

Un delfinariu are un bazin in forma de cilindru cilcular drept. Pentru a oferi mai multe reprezentati, bazinul este impartit in doua parti egale printr un perete dreptunghiular cu aria de 300 m patrati. Se stie ca raza bazei cilindrullui este de 15 m. Aflati inaltimea bazinului.
Answers
Answer:
Înălțimea bazinului este de 20 m
Step-by-step explanation:
Raza de bază a bazinului cilindric = lățimea peretelui dreptunghiular = 15 m
Suprafața peretelui dreptunghiular = lungime × lățime = 300 m²
300 m² = lungime × 15 m
lungime = 300 m² / 15m
lungime = 20 m
Lungimea peretelui dreptunghiular = înălțimea bazinului cilindric = 20 m
Prin urmare, înălțimea bazinului = 20 m.

The ratio of women to men working at a grocery store is 4 to 5. There are 16 women working at the store . What is the total number of people working at a grocery store?
Answers
Answer:
36 people
Step-by-step explanation:
The ratio of women to men working at a grocery store is 4 to 5.
The ratio =
Women : Men
4 : 5
The sum of the proportion is 4 + 5 = 9
There are 16 women working at the store .
Let us represent the total number of people working at a grocery store as x
Hence:
4/9 of x = 16 women
4/9 × x = 16
4x/9 = 16
Cross Multiply
4x = 16 × 9
x = 16 × 9/4
x = 36 people
The total number of people working in the grocery store is 36 people

If a certain cannon is fired from a height of 8.4 meters above the ground, at a certain angle, the height of the cannonball above the ground, h,
in meters, at time, t, in seconds, is found by the function h(t) = -4.91? + 30.5t + 8.4. Find the time it takes for the cannonball to strike the
ground.
Answers
Answer:
The time it takes for the cannonball to hit the ground is 6.49 seconds.
Step-by-step explanation:
You know that the height of the cannonball above the ground, h, in meters, in time, t, in seconds, is found by the function h(t) = -4.9t² + 30.5t + 8.4. You want to calculate the time it takes for the cannonball to hit the ground, that is, the time it takes for the bullet to reach zero height. So, being h(t) = 0 you have:
0 = -4.9t² + 30.5t + 8.4
To solve a quadratic function 0=a*x² + b*x +c, the expression is applied:
[tex]\frac{-b+-\sqrt{b^{2} -4*a*c} }{2*a}[/tex]
In this case, being a = -4.9, b =30.5 and c =8.4 you have:
[tex]\frac{-30.5+-\sqrt{30.5^{2} -4*(-4.9)*8.4} }{2*(-4.9)}[/tex]
Solving you get:
t1= -0.26 seconds and t2=6.49 seconds
Since time does not have a negative value, then the time it takes for the cannonball to hit the ground is 6.49 seconds.
